Definitions
- the invention relates to a roller for a manually movable transport trolley, which is suitable for transportation on passenger moving walks, with a wheel fork which carries an impeller and with an independently working locking device which is effective when the transport trolley is on a passenger moving walk ,
- the invention further relates to a hand-movable transport trolley, which is suitable for transportation on passenger moving walks and is equipped with castors, each of which has a wheel fork carrying an impeller and which are equipped with an independently operating locking device, each locking device being effective when the Dolly located on a passenger walkway.
- Rollers of the type mentioned at the outset are required in the case of transport carriages which can be moved by hand, for example in shopping carts, if these carriages are also to be transported on known passenger moving walks.
- the locking rollers prevent the trolleys from rolling away during downward and upward travel thanks to their locking device. Suitable rollers are e.g. described in more detail in DE 26 56 322 C2 and in EP 0 378 389 B1.
- the solution to the problem is that a locking device which can be actuated by the foot is arranged on the wheel fork and that the locking device and the locking device are connected by means which, when the locking device is effective, are intended to prevent the braking function of the locking device.
- the roller has means which prevent the braking function of the locking device when the locking device is effective, it is not possible to activate the locking device when there is a transport carriage on a moving walk. If you could activate the locking device, this would have fatal consequences if a transport vehicle is about to leave the passenger walkway. Then the transport wagon blocked with the locking device would get stuck at the end of the pedestrian walkway at its crest and subsequent people and wagons would inevitably be transported from the moving passenger walkway to the obstacle in front of it.
- the proposed roller thus leaves an abuse or a result of ignorance- the activation of the locking device when transporting a trolley on a moving walk does not, which in addition to the advantageous function mentioned above proves to be a further useful property.
- FIG. 1 shows a roller in which the locking device is formed by a brake foot
- FIG. 2 shows a roller in which the locking device has a feeler wheel.
- Fig. 1 shows a roller 1, the basic structure of which is based on those rollers which are manufactured by the applicant under the designation "type 3". The following description therefore concentrates preferably on those technical features which have been newly added in the sense of the invention
- the roller 1 has, in a known manner, a wheel fork 2 which carries an impeller 5 located on a horizontal axis 6.
- the impeller 5 is formed by two discs 7 which are arranged on both sides of a support body 9 which is supported by an axle pin 10
- the axle pin 10 connects the two legs 3 of the wheel fork 2.
- the wheel guest 2 closes off at the top with a cylindrical housing section 4, in which there is a deep groove ball bearing located on a vertical axis 8.
- the roller 1 can thus be moved mounted on a transport path (36), (Fig. 3), as a so-called “swivel castor” pivot about the vertical axis 8.
- a wheel fork 2 is also possible which has no housing section 4 and thus also no grooved ball layer.
- castors 1 are known under the name "fixed castors”.
- the castor 1 has a locking device 11, which is effective in a known manner when the castor 1 is attached to a hand-movable T ⁇ a ⁇ sport. (36) is located on the treadmill 33 of a passenger moving walk 32.
- the treadmill 33 is indicated schematically in the drawing, the two running disks 7 are immersed in two longitudinal grooves 34 of the barrel barides 33 and the roller 1 is seated with a brake foot 12 which is part of the locking device 11, on the longitudinal webs 35 of the treadmill 33. In this position the Roller 1 locked on the treadmill 33. It cannot roll away.
- the locking device 11 is located in the lower region of the support body 9.
- the support body 9 has a receptacle 13 which is accessible from below and in which the brake foot 12 is located.
- a compression spring 14 supported in the receptacle 13 acts on the brake foot 12 from above.
- the brake foot 12 can be moved a short distance in the vertical direction. In the position shown, it is pushed up.
- the compression spring 14 presses the brake foot 12 down a short distance.
- the brake foot 12 remains in this position when the locking device 11 is not effective.
- an opening 15 leads upwards in the support body 9 and out of the support body 9 there.
- a rod 16 is attached to the brake foot 12 and is arranged in the opening 15.
- a known, foot-operated locking device 19 is attached to the wheel fork 2 between the two legs 3 of the wheel fork 2.
- the locking device 19 mounted on a horizontal axis 20 has an actuating section 21 and a braking section 23.
- the mechanical structure located between the actuating section 21 and the braking section 23, that is to say corresponding individual parts, are selected in a known manner in such a way that the brake section 23 is tensioned with the foot on the actuating section 21 and on the impeller 5 and / or on, in the event of a corresponding action presses the running discs 7.
- the impeller 5 is braked.
- the braking section 23 can be released in a likewise known manner by corresponding action of the foot on the actuating section 21 and the braking effect can thus be canceled.
- At the upper end of the rod 16 there is an active part 17 which is supported with its back 18 on the braking section 23.
- the brake foot 12 presses the braking section 23 upwards so far via the rod 16 and the active part 17 that the braking function of the locking device 19 is canceled. If the roller 1 is removed from the treadmill 33, the compression spring 14 presses the brake foot 12 said piece down with the effect that the rod 16 and the active part 17 are also moved downward by this piece, see double arrow.
- the active part 17 is connected to the braking section 23 and the braking section 23 in turn to the actuating section 21. bound that the braking section 23 maintains its upward position after moving the active part 17. This property is very important. If a transport trolley (36) equipped with a roller 1 leaves the treadmill 33 of a passenger moving walk 32, then the locking device 19 must not take effect on its own.
- the interaction between the active part 17, the braking section 23 and the actuating section 21 is therefore designed, for example by self-locking, ratchet function, snap function and the like, such that the behavior of the locking device 19 just described is guaranteed.
- the locking device 19 can only be reactivated and the impeller 5 braked only when the actuating section 21 is actuated again with the foot.
- the means 24, which are suitable for preventing the braking function of the locking device 19 when the locking device 11 is effective, in this example are at least the brake foot 12, the compression spring 14, the rod 16 and the active part 17. To optimize this function, suitable means can be used Way further parts counting to the locking device 19 are claimed or consulted.
- the basic structure of the roller 1 shown in FIG. 2 is based on that of the roller manufactured by the applicant, which is known under the name "Type 4".
- the roller 1 has a wheel fork 2 equipped with or without a deep groove ball bearing, which carries a running thread 5 located on a horizontal axis 6.
- a traction wheel 25 rotatable about a horizontal axis is provided, which is part of a locking device 11, which is largely located inside the running wheel 5.
- the drawing again shows the treadmill 33 of a passenger moving walk 32.
- the running wheel 5 of the caster 1 stands on the longitudinal webs 35 of the treadmill 33, while the feeler wheel 25 is immersed in one of the longitudinal grooves 34, so in a lowered position ge is located. In this position the locking device 11 is effective.
- a transport trolley (36) equipped with a roller 1 is thus locked on the treadmill 33. If the transport carriage (36) and thus the roller 1 leaves the treadmill 33, the feeler wheel 25 is pushed up a little so that the effect of the locking device 11 is canceled and the wheel 5 can be rotated.
- a trigger wheel 26 Arranged above the impeller 5 and between the legs 3 of the wheel fork 2 is a trigger wheel 26 which is carried by a two-armed lever 27 and which is fastened to the wheel fork 2 so as to be pivotable to a limited extent about a horizontal axis 29.
- the trigger wheel 26 is intended to roll on the circumference of the feeler wheel 25.
- a known, foot-operated locking device 19 On the wheel fork 2 and in the vicinity of the lever 27, a known, foot-operated locking device 19 is again provided, which has an actuating section 21 and a braking section 23. As already described in Fig. 1, the parking brake 19 can be locked with the foot and released again. Depending on the impeller 5 is thus prevented from rotating or freely rotatable.
- the lever 27 is supported under the action of a torsion spring 28 on the horizontal axis 29 such that the trigger wheel 26 is always pressed against the feeler wheel 25. If the feeler wheel 25 is moved in the vertical direction, the lever 27 pivots, see double arrow. In the lowered position of the feeler wheel 25, as drawn, the lever 27, with its end 30 opposite the release wheel 26, presses against the underside 22 of the actuating section 21 and thus prevents actuation of the actuating section 21 in the sense of a locking of the locking device 19. This locking is released, when the feeler wheel 25 is moved upward at the end of a passenger moving walk 32. Then the end 30 of the lever 27 is pivoted away from the actuating section 21, so that it can again be influenced and moved with the foot.
- the means 24, which prevent the braking function of the locking device 19 when the locking device 11 is effective, in this example are at least the feeler wheel 25, the release wheel 26, the lever 27, the torsion spring 28 and the axis 31 on which the lever 27 is mounted.
- Fig. 3 shows a manually movable trolley (36) which is suitable in a known manner for transportation on passenger walks (32).
- the transport trolley (36) designed here as a shopping trolley has two or three conventional rollers (1) in the example, which are equipped with a self-operating locking device (11).
- the locking device (11) of each roller (1) is effective when the trolley (36) is on a passenger walkway (32).
- the locking device (11) and the locking device (19) are connected by means (24) which, when the locking device (11) is effective, are intended to prevent the braking function of the locking device (19), cf. also the descriptions of FIGS. 1 and 2.
